ADELMER MARCUS BATES, OF CHICAGO, ILLINOIS, ASSIGNOR TO BATES VALVE BAGCOMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF WEST VIRGINIA.

VALVE-BAG.

Specification of Letters Patent.

Patented Aug. 18, 1914.

To all 'whom it may concern Be it known tha-t I, ADELMER M. BATES, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented a certain new and usefulImprovement in Valve-Bags, of which the following is a specification.

My invention relates to a valve bag and is particularly applicable tothe case of large and heavy bags where the valve is to be applied to anotherwise completed or finished bag.

It is illustrated in the -accompanying drawings, wherein- Figure 1 is aside elevation of a bag with parts broken away; Fig. 2 is an edgeelevation of a collapsed ba with the valve tube open; Fig. 3 is asimilar elevation with the bag extended and the valve collapsed; Fig. 4isa perspective of the valve tube.

Like parts are indicated by the same letter in all the figures.

A, A are the sides of the bag which consists in this case of a longblank Whose two parts are folded upon each other to form the sides ofthe bag and whose two side edges are then stitched at B, B so as to forma bag with the mouth open at C.

D is a tube of valve-making material which is securely stitched to theseparated edges of the bag sides A, A, at E. The upper portion is alsosecured in any desired manner, but preferably bfy a series of quiltingseams, F, F, to the olded ed e or the permanently closed or upper end othe bag.

Such bags, and others differing in details but of vthe Same generalnature are easily made in large quantities at small expense, and theyare commonly intended to be folded at the large open end. The open end Cmay be closed in any desired manner as by the wire tie G or by apermanent or removable closure, but for the purpose which I now havespecially in mind, these bags are commonly closed before they are filledby a temporary closure. It is to such bags when they are. to be filledthrough a valve opening that my invention relates.

- The seam for a short distance from the folded edge or permanentlyclosed end of the bag is open and a piece of fabric shaped like a tubeis inserted. The end of the tube lls the aperture made in the bag byopening the seam, and the end of the tube and edges of the bag aresecurely sewed together. The

upper portion of the tube is now securely attached to the folded edge ofthe bag wlthin the latter so that the fabric of the bag and the tube arequilted together and thus each reinforces the otheri A very considerablenumber of my valve bag filling machines and apparatuses are constructedso that for satisfactory and successful operation a stream of materialshould be poured or forced into'the bag at the top or upper edge on 4aline approximately at right angles to the length of the bag. It isequally im ortant in many of my machines that the ag should more or lessbe supported on the filling tube which enters the bag and is adapted toreceive its .outer or folded or permanently closed end or edge. It is toprovide for these conditions that my invention is particularly adapted,and in the case of heavy bags where the bag hangs upon the tube, it ishighly, important that the fabric of the bag should be strong and ifpossible reinforced. Itis very diflicult if not impossible to fold theotherwise finished bag in any such way a's to produce a practicablehorizontal filling tube. IVe have solved these difliculties and provideda form of bag which is entirely practicable for all sizes, thoughperhaps' especially adapted for large bags or such as are to be filledwith considerable quantities of material.

I claim:

1. A valve bag comprising a body having an opening near one end incombination with a separate flexible valve tube inserted in said bagafter the same isr finished, its end secured to the edges of the openingand its side secured to the inside of the bag end.

2. A valve bag comprising a body having an opening near one end incombination withl a separate flexible valve tube inserted I in said bagafter the same is finished, its end secured to the edges of the openingand a part of its side Walls secured to the inside ofthe bag end.

3. A valve bag comprising a body having an opening near V,one end incombination with a separate cxible valve tube inserted in-said bag afterthe same is finished, its end secured to the edges of the opening andapproximately half of its side walls secured to the inside of the bagend.

4. A valve bag comprising a body having an opening near one end incombination with a seara-te said bag after the same :is finished,itsven'd secured to the edges of the'opening and approximately half ofits side walls secured to;

the inside of the bag end by a series of seams.

` 5. A. valve bag comprising .a body hv'- ng an opening near one end '1neomblnation HeXibe valve tube inserted V' e. A' valve' bag Comprising abody hvipg an opening near one end in combination with 15 a separateflexible valve ube inserted in said bag aer the sa-me's nshed5 its end,secured to the edges of the opening.

In testimony whereof, affix my signature in the presence of twoWitnesses this 5th 20 Y' day of October 1912.
